On top of that, they're offering an exclusive Ubisoft Holiday Pack with 14 games, all with 74% off of the suggested retail price. More information can be found on Steam's site.

So go for it, because the sale is up from now until January 2nd, 2012. There's a lot of gems to be had here, and the price cuts make it even more of a no-brainer. Besides, how the hell else are you going to escape from mundane conversations with distant family members over the holidays? With Assassin's Creed, that's how.
